'Seven fold' in the Bible

And if for this ye hearken not unto me, I will punish you sevenfold more for your sins,

And if ye walk contrary unto me, and will not hearken unto me, I will bring sevenfold more plagues upon you according to your sins.

then I'll certainly oppose you. I'll take vengeance against you seven fold on account of your sins.

I'll oppose you with vicious rage. Indeed, I myself will punish you seven fold on account of your sins.
